NULL is an invalid address and is inaccessible. If it is not NULL, then it must be pointing to some Node object as inside the constructor of the List class, we have initialized this pointer variable to NULL. If you use the next or back methods that move the current pointer, it will never point to NULL.

All queries in an SQL statement containing a UNION operator must have an equal number of expressions in their target lists. Change the first part of the query to a null or negative value so we can see what field will echo data back to us.


A name for the null pointer: nullptr (revision
A null pointer constant is an integral constant expression (expr.const) rvalue of integer type that evaluates to zero. A null pointer constant can be converted to In particular: § Distinguishing between null and zero. The null pointer and an integer 0 cannot be distin-guished well for overload resolution.
